Greetings; leds are something I'll have to plead less than a full understanding of.
So, if I connect these 2 channels of this sparkfun kit such that the anode of one is connected to the cathode of the other, effectively placing them in parallel, add a current limiter in series with the common of one end, do I need to also put in a reverse voltage protection diode, or will the one that needs to light up, will light up without being shorted out by the other polarity led across it? The C1G can put out sufficient currant (24 ma) but I believe its programming jumpers cannot allow both polarities, its a one or the other deal per data line, so I'll have to invert the signal to get the opposite drive external to the C1G, but that doesn't seem to be a show stopper. The idea is to have the 2 optos outputs in totem pole for a bidirectional drive +12 volts or 0 volts, both active on an exclusive basis into the Gemini controller. The question is, do I need to polarity protect the leds in the opto package? The pdf I downloaded on the opto package is less that informative on this particular detail.
